LSHTM Viral: Season 3 of our podcast puts vaccines under the microscope

Vaccines are the world’s route out of the COVID-19 pandemic and back to normality. But how do vaccines work? How do you create a new vaccine? And perhaps most importantly, how do you produce enough to vaccinate the entire world? Season 3 of our podcast takes listeners on that journey, from their development to implementation.

Available now, the new season of LSHTM Viral will explore issues and answer key questions on COVID-19 vaccines.

The first episode explores the importance of vaccines in unlocking the UK and the rest of the world. We chat to Prof John Edmunds, a professor of infectious disease modelling at LSHTM and member of the government’s Scientific Advisory Group for Emergencies (SAGE), as well as Dr Rosalind Eggo, who has worked extensively on COVID-19 transmission and public health interventions in the UK and internationally.

The second episode launched this week walks the listener through the history of how vaccines came to be, with Dr Gareth Millward from the University of Warwick and a former Research Fellow with the Centre for History in Public Health at LSHTM, alongside Prof Liam Smeeth, Dean of the Faculty of Epidemiology & Population Health and a GP in London.

In fortnightly episodes, the rest of the series will feature leading scientists from LSHTM and other renowned institutions who will take listeners through the history of the first vaccines, how they’re created in the lab, tested for safety, and manufactured at scale.

We’ll also explore issues surrounding the distribution of COVID-19 vaccines, including the concerning rise of vaccine nationalism. Listeners will hear from experts on vaccine hesitancy, who will tease apart the complex factors that affect public trust in medicine, including misinformation and marginalised communities.

The podcast team wants to hear questions and concerns members of the public may have about the new vaccines. Email your queries to, and health experts will answer as many questions as they can during each episode.

This series follows on from the extremely successful first and second seasons of LSHTM Viral, which discussed the outbreak of COVID-19, and the impact of climate change on our health. LSHTM Viral has had over 150,000 listeners in 170 countries, and is the 13th most popular science podcast in the UK on Spotify.
